May I draw your attention on two publications on the link of mercury in vaccines and amalgam ("silver") tooth fillings to autism and Alzheimer's? German researcher Dr Joachim Mutter published them in 2005 and 2004. In both conditions a genetic factor is involved. The fact that microwaves break down the blood-brain barrier (BBB) has been shown in many experiments (e.g Salford et al 2003). If the BBB is permeated, mercury in the body reaches the brain directly - most likely even in humans who don't have the genetic factor that makes them prone to suffer from either autism or Alzheimer's.
